Isolation and characterisation of compounds, 1-(2'-hydroxy-4'-methoxyphenyl)- 3-(4 ''-methoxyphenyl)-2-hydroxypropane-1,3-dione (1), 5-hydroxyflavone (2), 3,5,7,3',4'-pentahydroxyflavone (3), 3,5,7,2',4'-pentahydroxyflavone (4) and 5,7,3', 4'-tetrahydroxyflavone-3-O-rhamnoside (5) are reported from the air dried flowering buds of Bauhinia tomentosa Linn. Their structures are determined on the basis of extensive chemical and spectral evidences. Compound (1) is reported for the first time from the plant source. While compounds (2) and (4) are reported for the first time from this genus, compound (2) is reported for the second time from the natural source. [GRAPHICS] .
